I am creating a remote pendant with Stop/Pause/Play/ ESTOP buttons for our new UR20. These buttons have LEDs in them and I would like the red LED to be lit while the cobot is not running. Currently I have the LED in a configurable output and have the setting set to “High when not running”. The red light comes on when the cobot is not running but the Light does not turn off when the program is running. Is this a polyscope issue or am I doing something in correctly?

Thanks

Not exactly sure the nuance there. Doesn’t seem like you’ve done anything wrong. You could opt to just start each program with “set config output false” or else use the “High when running, low when stopped” option and take it through a normally closed contact contact of a relay to get its opposite effect.

Thanks, that’s what I was thinking. I ended up just turning off the output during the before start sequence

My thought is that it’s not suppose to go LOW otherwise they would have stated it in the “action” like “Low when Running, OTHERWISE high”. That’s my assumption. However I’m still learning!
